Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reversing device for reversing a tile raw material or the like after molding by 90 degrees.

The tile manufacturing process includes an inversion process in which the orientation of the extruded tile material, which is susceptible to plastic deformation, is inverted by 90 degrees and transported to the next drying process or the like.

The present invention relates to a reversing device that automatically performs the reversing process without causing any deformation to the tile raw material, and aims to automate the conventional reversing process manually and save labor.

Hereinafter, the reversing device according to the present invention (hereinafter referred to as the proposed device)
will be explained based on the embodiment shown in the drawings.

In addition, hereinafter in this specification, "front" refers to the left side of FIGS. 1 and 2, "back" refers to the right side of the same figure, "right" refers to the lower side of FIG. 1, and "left" refers to the upper side of the same figure. say.

Fig. 1 is a schematic plan view showing an embodiment of the present device, and Fig. 2 is a schematic right side view of the same. It is a crossing conveyor and consists of a wide belt conveyor.

A carrying means 3 is connected to the rear exit side of the crossing conveyor 1 via a fixed receiving plate 2.

The carrying means 3 includes two left and right belt conveyors 3a, 3a.
It is configured to support the lower surfaces of the formed green material 4 sent from the crossover conveyor 1 on both left and right sides while transporting it rearward.

Reference numeral 5 denotes an endless conveyance means for reversing provided behind the carrying means 3, and the endless conveyance means 5 includes a receiving surface having two receiving surfaces 6a and 6b with different mounting angles on the outer periphery. It consists of a conveyance chain 7.7 formed by fixing the mounting tools 6 at an appropriate pitch P, and the conveyance chain 7.7 runs along an arch-shaped delivery path B.

In the arched delivery path B, the central angle θ of the receiving end connected to the carrying-in means 3 and the delivery end connected to the carrying-out means 12 are substantially perpendicular.

Each receiving device 6 has a receiving surface 6a that connects the entrance passage A formed inside the belt conveyors 3a, 3a of the carrying means 3 with the horizontality of the carrying-out surface formed by the belt conveyors 3a, 3a. The receiving tool 6 moves diagonally upward from below while maintaining approximately the same horizontality, then passes through the arched delivery path B while gradually changing its attitude, and continues to The receiving surface 6b of the tool 6 moves obliquely downward in the exit passage C while maintaining substantially the same level, and finally the receiving tool 6 returns to the bottom of the conveying means 3.

Note that the conveyance speed of the conveyance chain 7.7 is set to 10 to 1.
When the speed is as high as 5 m/min, the radius of curvature R of the arched transfer path B is set to be 400 mm or more.

8 is a guide rail for the conveyor chain 7.7, 9 is a driving chain sprocket, 10 is a driven chain sprocket, and 11 is an idler for adjusting the tension of the chain 7.

A delivery means 12 connected to the endless conveyance means 5 is provided on the delivery end side of the arched delivery path B.
2 consists of two belt conveyors 12 a, 12 a arranged so as to sandwich the exit passage C of the receiving device 6 from the left and right, and the belt conveyor 12 a is arranged to sandwich the exit passage C of the receiving device 6 from the left and right, and the belt conveyor 12 It is configured to support both sides of the lower surface of the formed green base material 4 that is moving downward and to carry it out rearward.

At the exit end of the carrying out means 12, there are three endless bells) 13a.
A wide conveyance means 13 consisting of is connected.

14 is a driving means, and the driving means 14 is a driving source 15.
The output rotation from the transmission means 16 and the deceleration means R1 to R
4 to the driving pulleys 17, 18, 19 and the driving chain sprocket 9 to drive the conveying chain 7.7 of the endless conveying means 5 at the conveying speed V, and also to drive the transfer conveyor 1 and the inlet The conveyance speed of the means 3 is approximately vcosα (where α is the intersection angle of the belt conveyor 3a and the conveyance chain 7), and the conveyance speed of the unloading means 12 and the conveyance means 13 is approximately vcosβ (however, β is the intersection angle of the conveyor chain 7). and the intersection angle with the belt conveyor 12a).

D is a differential gear device for adjusting the timing when transferring the shaped green blank 4 from the carrying means 3 to the receiving tool 6.

Note that the carrying-in means 3 and the carrying-out means 12 are not limited to the above-mentioned structure;
A suitably structured carry-in means is capable of supplying the shaped green substrate 4 to the container, and is also capable of carrying out the shaped green substrate 4 for inversion placed on the receiving device 6 passing through the exit passage C. Of course, it is possible to use an appropriately structured carrying-out means.

Next, the effects of the present device will be explained.

The formed green material 4 that has been supplied from the transfer conveyor 1 to the carrying means 3 is placed on a receiving tool 6 that is being moved obliquely upward in the entrance passage A.
is transferred to the receiving surface 6a.

Next, as the shaped green material 4 transferred to the receiving tool 6 is transported by the transport chain 7, its posture is reversed approximately 90 degrees on the arch-shaped delivery path B, and backward at the transport speed ■. transported to.

The inverted shaped green material 4 that has come out of the delivery end of the arched delivery recording path B and has come to the exit path C is transferred to the delivery means 12 and carried out to the transport means 13; from there to the next process.

It should be noted that the object to be inverted in the device of the present invention is not limited to the above-mentioned shaped green substrate, but may of course be any suitable object such as a fired tile.

As described in detail above, the present device uses an endless conveying means formed by fixing receiving tools at appropriate pitches to move an arch-shaped delivery path whose central angle is approximately right angle when looking at the receiving end and the delivery end. Since it is connected to the delivery end side of the arch-shaped delivery path, it automatically turns over the molded raw material, etc., which is easily plastically deformed, and greatly saves labor in the turning process. Furthermore, when the radius of curvature of the arched delivery path is set to 400 mm or more,
The angular velocity of the receiving tool passing through the arched delivery path becomes slow, and the centrifugal force acting on the formed green material placed on the receiving tool becomes extremely small. Even when the raw material is conveyed at a high speed of 10 to 15 m/min, there are problems such as the formed green material jumping out from the receiving tool, or the shaped material moving and deforming on the receiving tool. This has the effect of being able to quickly turn over the formed green material, which is prone to plastic deformation, without causing any damage.
